My email account won't let me report abuse

My emails have constantly read that I have 836 and more emails unread in my box. I will have only a couple in my inbox.
When I go to report this to yahoo on any form where it says yahoo.ID it is faded out and when I click on the box to write in my email it zooms me out of the page.
I don't know how to contact yahoo to tell them as every email that I send them bounces back in a queue of some kind.
I am grateful to be writing this out and for once have someone read this.
Thank you for setting this site up.
